X52%S157; [目的]验证不同源汇型农作景观组合对削减农田泥砂、氮、磷排放的效果.[方法]于2014-2017年在浙江省选择蔬菜地-茭白田、蔬菜地-水田、果园-茭白田、桑园-水田和果园-荷塘等5种南方地区有代表性源汇型农作景观组合模式,进行定位观察,比较分析了其对泥砂量、总磷量、可溶性磷量、总氮量和可溶性氮量的减排效果.[结果]与"汇"处理前的"源"农田比较,5种源汇型农作景观组合农田泥砂和养分流失削减比例均在70％以上,平均削减率总磷量(90.63％)＞可溶性磷量(89.14％)＞泥砂量(88.72％)＞可溶性氮量(86.75％)＞总氮量(86."％).5种景观组合对削减排水中泥砂量、总磷量、可溶性磷量、总氮量、可溶性氮量的效果表现为果园-荷塘＞蔬菜地-茭白田＞果园-茭白田＞桑园-水...
